ProGet - Error scanning blob exception

[jw]

We are encountering the following exceptions, when pushing to the ProGet Docker registry:

Error scanning blob 487afa63fba9 (id=1793): The archive entry was compressed using an unsupported compression method.

System.IO.InvalidDataException: The archive entry was compressed using an unsupported compression method.

at Inedo.ProGet.Feeds.Docker.BlobScanner.DockerBlobScanner.ScanBlobAsync(DockerBlobs blobData, Stream blobStream, ILogSink log)

It appears that the exception is coming from blobs that are just docker manifests in JSON format which are not compressed.

The manifests are created and pushed with the docker manifest command.

Hi @jw ,

This error should not be logged and you can ignore it; we'll get it fixed in an upcoming maintenance release of ProGet via PG-2740

Cheers,

Thanks for the feedback and the fix.

Have a nice weekend.
